The proximal end of each second branch rib is connected to the second end of the fixing rod. The medical intra-cavity pressure apparatus enables stomach fundus compression area to be significantly increased, can provide low-pressure intermittent compression, and can ensure esophageal and fundal compressed mucosae's own blood supplies to avoid necrosis of the mucosae; after being implanted, the apparatus may be subjected to gastroscopy through hollow passages of the esophageal stent and stomach fundus umbrella, and diagnosis and treatment are made possible for the hemostasis of bleeding points under a gastroscope, except for hemostatic and compressed parts; the apparatus is convenient to place and remove; the apparatus can provide preventive therapy of bleeding for a patient with long-term compression therapy or severe esophageal varices, and is suitable for treating more indications.
Description
Technical field
The present invention relates to a kind of body cavity pressure or hemostasis device especially near alimentary canal stomach bottom.
Background technology
The world is every year because of the people of cirrhosis died about 1,200,000, and cumulative year after year, and most of reason is esophagus caused by cirrhosis
Therapy for Gastric Variceal Bleeding, it is medicine, apparatus, intervention operation and abdominal etc. to commonly use Hemostasis.It is heavy for acute
The acute stages treated of disease bleeding, first-selected conventional means international at present is still Sengstaken-Blakemore tube, also known as Sengstaken-
Blakemore tubes or Minnesota tubes hemostasiss by compression, minority doctor uses Linton-Nachlas tube (only
The stomach air bag of one about 500ml, without esophagus air bag) hemostasis by compression.For a long time, although above-mentioned hemostat device is clinical most of
Act as also being found that many problems during key player, but use in bleeding in esophageal and gastric varices, it is such as common
Secondary avulsion bleeding when complication includes the mucous membrane necrosis of esophageal-gastric bottom, mucosa ulcer, takes out, rare complications following is broken including esophagus
Split, suffocate air flue etc., other unfavorable aspects also include putting pipe difficulty, oppress invalid, compressing adjustment difficulty, balloon rupture, harm
Hinder gastroscope further to check etc..
In addition, as shown in figure 1, the stomach bottom 60 of human body alimentary canal and the end of oesophagus 50 close to.It is existing when the bleeding nearby of stomach bottom
Although having capsule pipe or other hemostat devices to enter at this carries out hemostasis by compression, its local pressure is generally unadjustable.Cause
This, during stomach end blood such hemostat device or device are just needed badly, and it can to stomach bottom bleeding part pressure applied
To be adjusted accordingly according to actual needs in hemostasis.
The content of the invention

Each adjust line 1 one end be connected with the near-end of second branch's umbrella frame 8, the other end then extend pass can umbrella 5 umbrella top
Opening and tubular support 3 hollow channel.For the damage for preventing from adjusting the distribution of line 1 and being likely to result in alimentary canal
Wound, the major part (referring to for its length) of these regulation lines 1 can be housed in a flexible pipe 11.
As shown in figure 3, the medical body cavity inside device for exerting of the present invention can also include can remove sleeve pipe or can extract cylinder
Set 2, it is coated at can maintain it in closed mode or contraction state on umbrella 5 and tubular support 3, and after being extracted
Be automatically releasable can umbrella 5 and tubular support 3 to form it into open mode or swelling state.But those skilled in the art can be with
Understand, it would however also be possible to employ any other suitable method come discharge can umbrella 5 and tubular support 3 open or expand to form it into
State.
Use and work of the medical body cavity inside device for exerting of the lower present invention near alimentary canal stomach bottom is briefly described below
Make process.
First, the device with jacket casing 2 is sent near gastral stomach bottom 60 via oral cavity or nasal cavity, Jing x lines or bed
Other ultrasound determines extracts out jacket casing 2 behind position, at this moment tubular support 3 and can the automatic expansion of umbrella 5 or it is normal open, due to even
The relative decrease external diameter of transition part 4 is connect, whole device is just fixed or be positioned at the relevant position at esophagus 50 and stomach bottom 60, and right
Cirso- herein carries out pressure hemostasis.Because whole device is formed with the hollow channel for running through up and down, therefore at this moment still
Other can be performed and check such as gastrocopy.In addition, the hemostasis device of the present invention even subsequently short-term can be retained in patient
Continue its anastalsis in vivo and do not affect its normal life.
If necessary to adjusting means to somewhere pressure applied near stomach bottom, corresponding regulation line 1 is just pulled up, from
And longitudinal chute upward sliding that the near-end of second coupled branch's umbrella frame 8 of drive is arranged along the excircle of hold-down bars 6, directly
To with desirable pressure respective heights at groove footpath narrowing portion 12 and by its backstop in this place.
Additionally, different line 1 can be adjusted adjust respectively can multiple orientation around the umbrella cover of umbrella 5 by adjusting successively
Pressure, approximately completely laminating presses to make cirso- of the whole umbrella cover to stomach bottom mucous membrane surface, so as to reach abundant anastalsis.
